As a novice developer , you may not be exposed to proxy mode, but in many frameworks the use of proxy mode is unknowingly used, such as the servlet filter chain, Spring AOP, and Spring MVC Interceptor. Therefore, understanding the proxy model is unavoidable for personal growth.In some cases, a customer does not want or cannot refer directly to an object, and an

One: Proxy modeThe role of proxy mode is to provide a proxy for other objects to control access to this object. In some cases, one customer does not want or cannot refer to another object directly, whereas a proxy object can act as an intermediary between the client and the target object.Second: The role of

JDK dynamic proxy ProxyGenerator generates the byte code file parsing of the proxy class, And JDK ProxyGenerator Through the previous analysis, we know that the Proxy class is generated through the ProxyClassFactory factory of the Proxy class. This factory class will call the generateProxyClass () method of the ProxyGe

Proxy mode is a common design pattern, and its characteristic is that the proxy class and the delegate class have the same interface, in the concrete implementation, there are static agents and dynamic agents. There is usually an association between the proxy class and the delegate class, and the object of a proxy clas

Introduce spring AOP before introducing three common proxy methods: Static agent, dynamic agent, Cglib agentAgent Overview:Proxy is a design pattern that provides additional access to the target object, which is accessed through the proxy. The benefit is that additional functionality can be enhanced based on the target object implementation. (extends the capabilities of the target object).Example: Star (Den

I found that one article is suitable.Summary: JDK's dynamic proxy is actually a combination of reflection and dynamic bytecode generated during execution; for Spring AOP, JDK dynamic proxy is also used (cglib is also used ).The following blogs are from the Internet:I.

here is simply a brief introduction to the use of the most basic agents. Agent, Popular Point said: is a person or an organization on behalf of another person or another agency to take action. In some cases, a customer does not want to or cannot refer directly to an object, and the proxy object can be End and target objects before they act as intermediaries.The proxy mode provides a
